Modulo Scheduling is an instruction scheduling technique that
is used by many current compilers. Different approaches have been
proposed in the past but there is not a quantitative
comparison among them, using the same compiling platform, benchmarks 
and architectures.

This paper presents a performance comparison of the most
relevant Modulo Scheduling techniques, based on a detailed quantitative
evaluation of them. The results point out which are the most
effective techniques for different architectures, which is useful
for compiler designers when choosing the most appropriate technique
for a particular processor architecture.
